Newswise — A new report from the World Meteorological Organization (WMO) shows that the world’s average temperature could breach a record 1.5 Celsius of warming compared to pre-Industrial Revolution levels.
News reports call the WMO announcement a critical warning of an average world temperature limit in the face of climate. Researchers indicate the threshold could be broken as early as 2027. A caveat: The breach will likely be only temporary. Nonetheless, as temperatures rise, ice in Antarctica and other places melts, setting up all but certain rises in sea levels. The problem will be further complicated by sinking coastal lands such as Chesapeake Bay in Virginia.
Virginia Tech geophysicist and environmental security expert Manoochehr Shirzaei studies climate change and uses publicly available satellite imagery to build maps of millions of instances of rising sea levels and coastal land subsidence.
“Sea level rise and land subsidence increase the hazards associated with hurricanes, storm surges, shoreline erosion, and inundation of low-lying coastal areas where the high density of population and assets amplifies the regions exposure to hazards.” He explains that land subsidence can also affect coastal structures’ integrity and increase the likelihood of failure.
Shirzaei says the solution varies from place to place based on the individual situation. It may involve upgrading protection facilities (i.e. dams), raising lands, maintaining and restoring nature-based protection (i.e. wetlands), controlling subsidence, improving flood resiliency, selective relocation of important infrastructure, or installing flood warning systems.
